I will fix shopify bugs and migrate scripts to shopify functions


About this gig
Shopify is phasing out checkout.liquid and legacy Scripts in favor of Shopify Functions if your store still runs old checkout scripts, discounts, or shipping customizations, they could break without warning. I help store owners fix broken Shopify bugs (theme errors, broken buttons, app conflicts, cart issues) and migrate outdated Scripts to the new Shopify Functions framework so your store stays compliant, stable, and fast.
Whether it's a small glitch slowing down your checkout or a full legacy Scripts migration before Shopify sunsets the old system, I dig into your code, find the root cause, and fix it cleanly no shortcuts, no broken themes.
What you get: clean bug diagnosis, functional fixes, safe Functions migration, and a store that works the way it should. I test everything live before handing it back, so you're not left guessing if it actually works.
Message me with your issue and I'll tell you honestly if it's a quick fix or a bigger job before you order.

FAQ
Do I need to give you admin/collaborator access?
Yes, I'll need Shopify collaborator access (no password sharing needed) to safely diagnose and fix issues.
What's the difference between a "bug fix" and a "Functions migration"?
A bug fix solves a specific error. A migration rebuilds your old checkout Scripts using Shopify's new Functions system so they keep working long-term.
Can you fix issues from theme apps like PageFly or GemPages?
Yes, I regularly resolve conflicts caused by page builders, third-party apps, and custom code.
What if the bug needs more time than the package covers?
I'll let you know upfront during the requirements review, before any work starts, no surprise fees mid-order.
Do you offer support after delivery?
Basic includes 24-hour post-fix support; Premium includes 7 days of support in case anything resurfaces.
